Radiosurgery & Radiotherapy of the Brain

Radiation therapy uses high-energy rays to treat tumors and other diseases. Radiation works by damaging the DNA inside cells and making them unable to divide and reproduce. The benefits of radiation are not immediate but occur over time. Aggressive tumors, whose cells divide rapidly, typically respond more quickly to radiation. Over time, the abnormal cells die and the tumor may shrink. Normal cells can also be damaged by radiation, but they can repair themselves more effectively than abnormal cells. The goal of radiation treatment is to maximize the dose to abnormal cells and minimize the exposure to normal cells.
